I have 10 unix servers and in that /home is common in all the unix servers and any update in /home of any server is getting reflected in all the servers.

How is this done? and also please let me know how to find out the mount point of /home in this case?

They are your ten servers, you tell me how you did this amazing thing. :) – Kaz Feb 21 '13 at 7:50

Look at the /etc/fstab file. This contains information on all the mount points that the system mounts automatically.

One line will almost certainly refer to /home and this is the one you will look for. It will probably look something like this:  /home   nfs     rw,nosuid,nodev     0 0

In this case we see from the third field that it is an NFS mount. Your file will tell you exactly what is going on in your case.

If you can't find the according lines in /etc/fstab it's also possible that your homes get mounted via automount. if you run this as root mount | grep home you should see all the currently mounted filesystems that have home in their path. by doing ps axu | grep automount you should see if there is an automount daemon running – mauro.stettler Feb 21 '13 at 7:31
There are other "network file system" or "distributed filesystem" possibilities too (AFS, SSHFS, etc.) – voretaq7 Feb 21 '13 at 20:14
Maybe he'll eventually come back and tell us all what he found. – Michael Hampton Feb 21 '13 at 20:15
